Widgets: align every widget to the exact logo palette (KC-19)

WidgetTheme now uses the true brand colors — accent RGB(232,98,42) on
the logo's dark RGB(26,29,34) — replacing a near-miss orange on slate.
Bars countdown, My Tasks, and Day Progress inherit it; Task Live
Activity drops its hardcoded accent/black tint for the theme; lock
screen rings tint brand orange.

+## KC-19 — Widgets: exact logo palette everywhere
+
+**Status:** In Progress (implemented & build-verified, pending device build)
+**Reported by:** User
+**Area:** Widgets
+
+### Description
+All widgets should match the brand orange theme of the logo exactly.
+
+### Fix
+- `WidgetTheme` now uses the precise brand palette: accent **RGB(232,98,42)**
+  (app `AppColors.accent`) on the logo's dark **RGB(26,29,34)** background —
+  previously a near-miss orange on a slate background.
+- Every themed widget (Event Countdown Bars, My Tasks, Day Progress) inherits it.
+- Task Live Activity: hardcoded accent → `WidgetTheme.accent`; background tint →
+  logo dark.
+- Lock-screen ring tints → brand accent (renders in color on StandBy/home).
+
+Files: `WidgetViews.swift`, `TaskLiveActivity.swift`.
